MarSurf XR 20 mit GD 120 Roughness measuring station
Product features
MarSurf XR 20, the perfect introduction to top-class surface metrology.
The PC-based instrument delivers all common surface parameters and profiles in accordance with international standards, both in the measuring room and in production. The powerful MarSurf XR 20 combines decades of experience in surface metrology with innovative technology, easy-to-read icons and user-friendly operator assistance.
A sampling length of up to 120 mm is possible in conjunction with the GD 120 drive unit.
In addition to surface roughness evaluations, profile and waviness evaluations can also be performed in this way.
